arXiv:2601.23207v2 Announce Type: replace Abstract: Understanding what graph neural networks can learn, especially their ability to learn to execute algorithms, remains a central theoretical challenge. In this work, we prove exact learnability results for graph algorithms under bounded-degree and finite-precision constraints. Our approach follows a two-step process. First, we train an ensemble of multi-layer perceptrons (MLPs) to execute the local instructions of a single node. Second, during inference, we use the trained MLP ensemble as the update function within a graph neural network (GNN).
The continuous advancements in AI research, particularly in deep learning and graph neural networks, are pushing the boundaries of what these models can achieve in complex algorithmic tasks.
This research provides a foundational understanding and a concrete method for GNNs to execute algorithms precisely, which is critical for their deployment in sensitive and high-stakes applications where accuracy is paramount.
The explicit demonstration of GNNs' capacity for exact algorithmic execution, even under constraints, suggests a path towards more reliable and auditable AI systems for computationally intensive tasks.
